FAQ

What macOS versions are supported?

Tiley requires macOS 14 (Sonoma) or later.

Why does Tiley need Accessibility permissions?

macOS requires Accessibility access to move and resize windows belonging to other applications. Tiley uses the Accessibility API solely for window management — no data is collected.

Can I change the grid size?

Yes. Open Settings from the menu bar to adjust the number of rows, columns, and the gap between cells.

Can I assign shortcuts to specific layouts?

Yes. Each layout preset (Maximize, Left Half, etc.) can have its own global shortcut assigned in Settings.

Is Tiley free?

Yes, Tiley is free and open source. The source code is available on GitHub.

What inspired Tiley?

Tiley's grid-based window placement was inspired by Divvy, a window manager we used and loved for years. When we needed a version built natively for Apple Silicon and modern macOS, we decided to reimagine that experience from the ground up as a free, open-source app.
